Title: Porous poly(tetrafluoroethylene) membrane
Inventor: NEWMAN DAVID E
IPC: B29C55/18
Filed: 1999-04-02
Abstract: PROBLEM TO BE SOLVED: To provide finely porous and ultrafine poly(tetrafluoroethylene) (PTFE) membranes having high permeability, superior mechanical strength, and excellently inactive to chemicals and to provide a relatively simple method for producing such membranes with high reproducibility. SOLUTION: A porous PTFE substrate having a first fine pore grade is produced and the substrate is pressurized between two compressive media to produce a porous PTFE membrane having a second fine pore grade. In this case, the method for producing such a porous PTFE membrane is so carried out as to make the second fine pore grade finer than the first fine grade and as to provide the resultant porous PTFE membrane with at least about 0.5 1/hr/m<2> /kPa water permeability. The PTFE substrate may be brought into contact with one or more fiber sheets and the substrate and fiber sheets may be pressurized by being passed between two calender rolls. After that, the obtained porous PTFE membrane may be extended and/or burned.

Title: Heat recovering device for burner heating type rotary furnace
Inventor: NISHIO KENICHI
IPC: F27D17/00
Filed: 1995-04-21
Abstract: PURPOSE: To recover Zn from steel scrap contg. Zn and to recover the steel scrap in a reusable state with good fuel efficiency by heating the steel scrap by using a first heating furnace and second heating furnace in and under a specific atmosphere and temp. conditions. CONSTITUTION: The scrap of galvanized steel sheets is charged into a first rotary furnace 1, where fuel is burnt in an oxygen deficient state of an oxygen ratio of 0.5 to 0.8 from a burner 3 and the scrap is heated by maintaining the in-furnace atmosphere at a reducing atmosphere. The Zn is thus recovered as Zn vapor without oxidation. The high-temp. waste gases contg. noncombustible gases, such as Co, discharged from the first rotary furnace 7 are charged by a duct 5 into a second rotary furnace 2, to which the air is supplied from a nozzle 6 and where the high-temp. Co-contg. waste gases are burned in the state of an oxygen ratio 1.  The Zn-contg. steel scrap in the second rotary furnace 2 is preheated to the oxidation temp. of Zn or below by the combustion heat formed in such a manner and the heat quantity possessed by the waste gases themselves, and thereafter, this scrap is transferred into the first rotary furnace 1. The Zn is thus recovered with the excellent thermal efficiency and the Zn-free steel scrap usable as a steel making source is recovered.

Abstract: PURPOSE:To make distance of displacement and its direction measurable and to contrive simplification and miniaturization of the construction, by, between a reflecting surface on a specimen and the extreme and of an optical fiber, installing a lens in a distance from its end shorter than the focal length. CONSTITUTION:This sensor is composed of sensor unit 1 and measuring unit 10 and they are connected with polarizing surface maintaining optical fiber 20 and a lens 3 is installed in a position shorter than the focal length from the extreme end of the optical fiber. A beam of light irradiated from the fiber 20 and transmitted through the lens 3 is dispersed and it is irradiated into a mirror 4a and reflected. Intensity of its signal light is weakened with the retarded distance of the mirror 4a and as the reference light is kept constant independently on the mirror 4a, the maximum value of the interference light decreases with the retarding mirror 4a, causing increase of the minimum value. From these changes, displacement direction of the mirror 4a can be identified. In the meanwhile, a beam of interfering light reflected by a beam splitter 12 is converted into an electric signal by a light-receiving element 14 to be counted by a counter 17. Thus, the amount of displacement is measured with a unit of lambda or lambda/2.

A switch Ew of this electrode E is determined so as to satisfy the relation of an expression I. For a track width Tw, the detected electrostatic capacity change by the electrode E is not fluctuated, in comparison with the case of Ew<Tp, even by the inclination, etc., of a disk surface during the tracking by a magnetic head H which satisfies the condition of an expression II. Then, the recording and reproducing can be always executed on the basis of the satisfactory tracking.

Title: Hands washing delivery pipe connection structure of flushing tank
Inventor: NAKAMURA KAYOKO
IPC: E03D9/00
Filed: 1997-04-15
Abstract: PROBLEM TO BE SOLVED: To prevent a holder and a connecting pipe part from being damaged by installing, at a delivery pipe base end part, a guide which is formed so that it surrounds the delivery pipe base end part, in which the connecting pipe part is fitted closely, and of which diameter is increased downward. SOLUTION: A rubber cap 40A provided integrally with a tapered guide 60 is used. A connecting pipe part 42 is guided by a guide 60, and close-fitted securely into a delivery pipe base end part 34. When a tank cover 14 is put on a tank main body 12 with the tank cover 14 shifted remarkably from the tank main body so that the guide 60 is shifted from the connecting pipe part 42, the connecting pipe part 42 is not fitted closely into the delivery pipe base end part 34. However, when the tank cover 14 is put on the tank main body 12 with normal care, the connecting pipe part 42 is always guided by the guide 60, and close-fitted smoothly into the delivery pipe base end part 34. Thus the connecting pipe part can be inserted smoothly into the delivery pipe base end part, and the workability to put the tank cover with washing bowl on the tank main body is increased.  In addition, a holder and delivery pipe main body are prevented from being damaged.

Abstract: PURPOSE:To easily perform the adjustment of current amplification factor by previously containing a required amount of O2 in the base layer of an NPN type semiconductor element wherein heat treatment is done after the formation of an emitter layer and O2 is made as donor. CONSTITUTION:A P<-> epitaxial layer 2 is stacked on an N<+>-type Si substrate 1 and after implanting O2 ion in the layer 2, the ion is diffused by high temperature treatment. After forming an emitter layer 3 by selectively implanting P ion on the surface, low temperature treatment is applied in succession.
